[0001] The present invention relates to a system for handling fishing gear, viz. the transfer of fishing gear in the form of a net into a bin aboard a vessel, and is particularly intended for use aboard pod or purse seine vessels in which it is of importance that gear, such as a seine which is to be hauled after use, may be cleared for new setting as quickly and simply as possible.
[0002] In connection with fishing gear provided with weights or sinkers along one edge, i.e. the ground, and with floats, such as cork floats, along the other edge, it is of importance that the gear, during setting, be disposed in an orderly manner in the gear bin, with the ground edge along one side of the vessel and the buoyed edge on the other. It is now usual for the gear to be drawn by means of a winch at one side of the vessel, then passed over an elevated pull roller arrangement at the end of a boom, and thence downwardly into a bin in which the gear is placed in an orderly manner by the crew, a task which is both heavy and cumbersome, as the gear is arriving at a relatively high speed, and may be very heavy.
[0003] A prior attempt to reduce this task has been made in DE-A-2338356 which discloses a system for handling a fishing net in a bin, wherein the top line of the net is pulled by and between two rotating ball rollers placed at a high point aboard the vessel and by two others rotating ball rollers, which are suspended lower and perform swinging movements.
[0004] The present invention relates to a system of the type which comprises a winch for hauling the net and a pull roller disposed at an elevated position relative to the winch for transferring the net to the bin, and which has a net positioning means caused to swing and situated between the pulling roller and the bin, the purpose of the invention being also to effectively avoid or substantially reduce the heavy manual labour of the prior systems. This is achieved, according to the present invention by the fact that the net positioning means is a net positioning chute extending downwardly between the pulling roller and bin, down which net from the pull roller is free to fall under its own weight due to gravity into the bin, means being provided to cause the net positioning chute to perform a swinging movement relative to the pulling roller in mutually angularly displaced planes. In such a system, the gear may be placed or stowed in orderly runs or turns in the bin, so that it may subsequently be set without forming tangles or other disorder.
[0005] The system embodying the invention preferably uses a net positioning chute in the form of a tube, which may be telescopic, and which is adapted to cooperate with jack means adapted to cause the tube to perform swinging movement for guiding the positioning of the gear in the bin.
[0006] In order that the invention may be more readily understood, an embodiment of a system applied to a pod or purse seine vessel will now be described with reference to the accompanying drawings, in which:-
Fig. 1 is a side view of the system;
Fig. 2 is a plan view of the system;
Fig. 3 is a view of the system as seen from the left in Fig. 1, i.e. in the fore and aft direction of the vessel; and
Fig. 4 is a side view of a detail of the system.
[0007] In the drawing, 1 is the aft portion of a fishing vessel, in which a bin 2 is arranged for the reception of a net which may be hauled in by means of a winch 3 at the side of the vessel. Inboard of the winch 3, the net is carried through a tube 4 over a pull unit 5 positioned at an elevated position aboard the vessel, for instance at the end of a boom, and is then conveyed to the bin 2. The seine is to be set out from the bin 2.
[0008] The pull unit 5 is associated with a net positioning chute extending downwardly between the unit 5 and the bin 2, in the form of a tube 6, down which the net is free to fall or slide under its own weight due to gravity. The tube may be monolithic, in one piece, or, as shown, telescopic so as to adapt to the distance between the unit 5 and the various points in directions athwart and fore-and-aft of the vessel, where the net is to be placed in the bin, and to the amount of net stowed, for example piled, in the bin 2. The tube 6 is provided with an inlet collar 7, and an outlet nozzle 8 which may be provided with means 9 (Fig. 4), coaxial with the tube 6 and rotatable about the longitudinal axis thereof, adapted to twist the net so as to facilitate the positioning of the net in the bin 2.
[0009] Means are provided, associated with the tube 6, for the purpose of varying the length of the tube 6 and for swinging the same relative to the pull roller in mutually displaced planes, i.e. in athwart and fore-and-aft directions during the hauling of the net and the placing of the same in the bin 2. The latter means comprises jacks, for example hydraulic piston-and-cylinder means 10, 11 and 12 as shown, which respectively effect adjustment of the tube length, and swinging of the tube 6 in athwart and fore-and-aft directions so that the net is placed in the bin 2 with the ground edge of the net towards the same side of the vessel as the winch 3 and the buoyed edge towards the opposite side. Thus, utilisation of the bin is maximised, and the subsequent paying out of the net may be performed without difficulties.
